Schistosomiasis in migrant children and adolescents in a paediatric tropical referral unit in Spain: diagnosis and long-term management challenges.

Globalisation and population movement have led to an increasing number of migrant children residing in areas non-endemic for schistosomiasis. However, diagnosing and managing schistosomiasis in children remain controversial. This study aims to investigate the prevalence of schistosomiasis in migrant children and to describe the diagnostic approach and management strategies, including long-term follow-up, to explore the potential role of serological tests in evaluating treatment response.

Changes in immunoglobulin levels during clozapine treatment in schizophrenia.

Background And Hypothesis: Use of clozapine in treatment-resistant schizophrenia is often limited due to risk of adverse effects. Cross-sectional associations between clozapine treatment and low immunoglobulin levels have been reported, however prospective studies are required to establish temporal relationships. We tested the hypothesis that reductions in immunoglobulin levels would occur over the first 6 months following initiation of clozapine treatment.

Mental Health in Children, Adolescents, and Youths Living with Perinatally Acquired HIV: At the Crossroads of Psychosocial Determinants of Health.

Here, we aim to describe mental health (MH) in a cohort of children, adolescents, and young adults living with perinatally acquired HIV (PHIV) in Spain and explore the treatment gap for mental disorders. We also aim to analyze the potential association between MH issues to psychosocial risk factors (PSRFs) and identify management priorities. We conducted a descriptive transversal study that included all cases of PHIV under follow-up in a reference hospital in Madrid.

Impact of Coronavirus Pandemic on Tuberculosis and Other Imported Diseases Screening among Migrant Minors in Spain.

Background: In recent decades, the increase in population movements has turned the focus to imported diseases. The COVID-19 pandemic has negatively impacted the access to health care systems, especially in highly vulnerable populations. We address the effects of the pandemic on the health screening of migrant unaccompanied minors (UM) in Spain.

Dual latent tuberculosis screening with tuberculin skin tests and QuantiFERON-TB assays before TNF-α inhibitor initiation in children in Spain.

Unlabelled: Tumor-necrosis-factor-α inhibitors (anti-TNF-α) are associated with an increased risk of tuberculosis (TB) disease, primarily due to reactivation of latent TB infection (LTBI). We assessed the performance of parallel LTBI screening with tuberculin skin test (TST) and QuantiFERON-TB Gold In-Tube assays (QFT-GIT) before anti-TNF-α treatment in children with immune-mediated inflammatory disorders in a low TB-burden setting. We conducted a multicenter cohort study involving 17 pediatric tertiary centers in Spain.

Nutritional Supplementation to Increase Influenza Vaccine Response in Children Living With HIV: A Pilot Clinical Trial.

Aims: Vaccine response is poor among children living with HIV. The gut microbiota has been identified as a potential target to improve vaccine immunogenicity, but data are scarce in the context of HIV infection.

Methods: Pilot, double-blind, randomized placebo-controlled trial in which 24 HIV-infected children were randomized to receive a mixture of symbiotics, omega-3/6 fatty acids, and amino acids or placebo for 4 weeks, each in combination with ART, and were then immunized against influenza.

Comparison of pneumonia features in children caused by SARS-CoV-2 and other viral respiratory pathogens.

Background: Pneumonia is a frequent manifestation of coronavirus disease 2019 (COVID-19) in hospitalized children.

Methods: The study involved 80 hospitals in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Spanish Pediatric National Cohort. Participants were children <18 years, hospitalized with SARS-CoV-2 community-acquired pneumonia (CAP).

HIV HGM biobank as a research platform for paediatric infectious diseases and COVID-19 pandemic.

Aim: The initial cases of COVID-19 appeared in December 2019 and Spain was one of the most affected countries during the first wave (March to June). Since then, HIV HGM BioBank has been restructured as an established Paediatrics and Adults HIV_COVID-19 BioBank that aims at the long-term storage of samples obtained from not only HIV-1, but also from COVID-19 patients and HIV-1_COVID-19 coinfected patients.

Methods: HIV HGM BioBank holds high quality biological samples from newborns, children, adolescents and adults with their associated clinical data.

Screening for parasites in migrant children.

Background: Globalization has pushed population movements in the last decades, turning imported diseases into the focus. Due to behavioral habits, children are at higher risk of acquiring parasitosis. This study aims to investigate the prevalence of parasites in migrant children and factors associated with parasitic diseases.

Prevalence of nonalcoholic fatty liver disease using noninvasive techniques among children, adolescents, and youths living with HIV.

Objective: The prevalence of subclinical liver abnormalities is high among people with HIV, but data regarding perinatally HIV-infected children and adolescents (PHIV) are scarce. Noninvasive image techniques offer an opportunity to address nonalcoholic fatty liver disease (NAFLD) in a population in which the scores validated for adults have not been tested.

Design: Prospective cross-sectional study including PHIV and uninfected controls.

Human Microbiome in Children, at the Crossroad of Social Determinants of Health and Personalized Medicine.

The evolving field of microbiome research offers an excellent opportunity for biomarker identification, understanding drug metabolization disparities, and improving personalized medicine. However, the complexities of host-microbe ecological interactions hinder clinical transferability. Among other factors, the microbiome is deeply influenced by age and social determinants of health, including environmental factors such as diet and lifestyle conditions.

Eosinophilia in Migrant Children: How Should We Proceed?

Background: The diagnostic approach to eosinophilia is complex, given the numerous reported etiologies. Intestinal parasites (especially helminths) are a concern in children from high-burden settings. We describe the diagnostic approach and clinical management of eosinophilia in a cohort of migrant children.

Acute bronchiolitis and respiratory syncytial virus seasonal transmission during the COVID-19 pandemic in Spain: A national perspective from the pediatric Spanish Society (AEP).

Introduction And Objectives: The COVID-19 pandemic and the widespread associated use of non-pharmaceutical interventions have impacted viral circulation and the incidence of respiratory tract infections. We compared Pediatric Emergency Department visits, bronchiolitis admissions, and respiratory syncytial virus (RSV) cases in 2020 with those documented for the preceding four years.

Methods: This was a retrospective multicentric national survey study, driven by the Pediatric Spanish Society, and gathering monthly data from Spanish hospitals between 1st January 2016 and 31st December 2020.

Alterations in Taenia crassiceps cysticerci cytoskeleton induced by nitazoxanide and flubendazole.

Cysticercosis is the presence of Taenia solium larval stage in tissues such as central nervous system, skin, muscles and eye globe. The current treatment is based on albendazole and praziquantel which already present resistance reports. Therefore, the search for alternative treatments is paramount.

Prevalence of M184V and K65R in proviral DNA from PBMCs in HIV-infected youths with lamivudine/emtricitabine exposure.

Objectives: We analysed the prevalence of M184V/I and/or K65R/E/N mutations archived in proviral DNA (pDNA) in youths with perinatal HIV, virological control and who previously carried these resistance mutations in historic plasma samples.

Methods: We included vertically HIV-infected youths/young adults aged ≥10 years in the Madrid Cohort of HIV-1 Infected Children and Adolescents, exposed to lamivudine and/or emtricitabine, with M184V/I and/or K65R/E/N in historic plasma samples, on antiretroviral therapy (ART), virologically suppressed (HIV-1 RNA <50 copies/mL), and with available PBMCs in the Spanish HIV BioBank. Genomic DNA was extracted from PBMCs and HIV-1 RT gene was amplified and sequenced for resistance testing by Stanford HIV Resistance tool.

Is there autochthonous strongyloidiasis in Spanish children?

Strongyloidiasis, a neglected helminthiasis, is more prevalent in tropical/subtropical areas. However, sporadic autochthonous cases have been described around the Mediterranean coast. We performed a retrospective descriptive study in a referral Spanish Center for Pediatric Tropical diseases.

Combined treatment with immunoglobulin and valaciclovir in pregnant women with cytomegalovirus infection and high risk of symptomatic fetal disease.

Introduction: Congenital cytomegalovirus (CMV) infection is one of the most common during pregnancy. The infection, particularly in the first trimester, is associated with important sequelae in up to half of the children. Valaciclovir and immunoglobulin have been tested separately for the treatment of fetal CMV infection with relative success.
